Assiouon, BY MESNE ASSIGNMENTS, TO THE LUDLOW TYPOGRAPH COMPANY, OF PITTSBURG, PENNSYLVANIA, A CORPORATION OF MAINE.

Application filed January 27,

To all whom Ill; may concern: Be'it known that I, WASHINGTON I. LUD- Low, a citizen of the United States, and a of Ouyahoga, j State of Ohio, have invented certain new and j l useful Improvements in Typographs, of which I hereby-declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to which it appert'ains to make and use the same. My invention relates to improvements in typographs or mechanism for assembling matrices representing characters for printing, before a casting box, to form slugs or bars comprising a line of characters of the width I of a-column of printed matter, and the obto simplify the mechanism required in the various operations of handling'the several matrices, conveyingthem to their respective positions, aliningarul justifying them and returning them to their original stations without mixing or confusing the numerous parts.

My invention consists in the various devices, the combination and arrangement of parts and construction of the several details as hereinafter described, shown in the accom'panying drawings, and specifically pointed out in the claims.

p In the accompanying drawings, Figure 1 is a plan view of the entire.device,'showing the composer closed after assembling the matrix bars and locked to alino them; Fig. l is a longitudinal section. of the same on line m w; Fig. 3 is a central longitudinal section of the same through the composer; Fig. 4 is an enlarged plan of the composer and trough containing the matrices showing-a portion of the bed of the machine, on which the composer rests; Fig. 5 is an enlarged view of the opening in the top of the machine bed showing to compose a line of type over the casting slot, and some of the matrices arranged to justify the line. This view also shows a sliding detent adapted to adjust the width of the-printed column; Fig. 6 isa perspective view of the composer detached from the other parts; Fig. 7 is a central transverse section of the same; F ig..S is an enlarged transverse section of the machine bed, showing the composer and matrices in j section and the detent. which adjusts the Specification of Letters Patent.

width of column; Fig. 9 is a perspective view of a tapered matrix bar; Fig. 10 is an enlarged plan view of one end thereof; Fig. 11 is a perspective view of a straight matrix bar having the pointed ends; Fig. 12 and 13 are enlarged views of upper and lower sides of one end thereof respectively: Fig. 14 is a plan view (somewhat enlarged from Fig. 1) showing the composer and matrix bars arranged to form a line of type above the casting slot, the detent and retaining spring for loose matrices; Fig. 15 is an enlarged central portion of Fig. 3 showing the mold slot, matrix bar, and composer in their proper relation when a line of type is cast. Fig. 16 is a perspective view of-the completed slug cast by the machine.

In these. figures,

1 is the frame or bed on which the devices are mounted, which accomplish my desired results; 2 is a rectangular opening in the cover thereof; 3 is a trough or receptacle which extends centrally through the entire length of the bed plate and in which are placed the matrix bars 4-, in the lower face or edge of these matrix bars are impressed or cut the matrices 5' of the characters which form the type, and centrally across the bottom of this trough is cut the slot 6 in which the nozzle 7 of the mold or. casting box is inserted to form the slug, the matrices being so arranged in the bars that those in adjacent bars will form a line registering with the nozzle of the mold box, so that a line of type cast therefrom will compose a line suitable for printing of the width of the column. The trough 2% in which these bars lie extends longitudinally across the frame, and the bars are provided with roo0 jecting pins 8 upon their upper faces wliich stand upright so as to be grasped by the hand, and are placed one in the center of each bar so that when the bars are manually thrown to the right or left the ins will serve as stops 9 5 for the bars against t 1e end walls 9 of the central open ng. This opening is of such a lengththat when the pins are in engagement with either end thereof, one-half of each bar will be ex osed to sight, and the other half will be cc erod by the upper plate or cover 100i the-frame.

As many matrix bars will be required as there may be characters in theprinted line,

. bars. read in unison with the characters on the matrix bars, and serve as guides to the relabars are assembled.

wide enough to inc ude the composer 12 b'eo tween its sides. and to'afl 'ordfree transverse movement for the composer across the opening 2 and the matrix bars 4 exposed therein...

This frame is moved freely by. means of racks 13, gears 14, and shaft with a milled head.

5 The composer is provided with as many teeth 16, and characters printed or exhibited on them as there are characters upon the matrix The characters on the teeth are to be tive positions of the pins on the bars which are inclosed in the composer slotswhen the I This composer 0011- s'tru'cted as shown in Fig.- 6is carrie'd by the 5 frame 11 and moves transversely of the bed or'at right angles to the the matrix bars. The pins on the matrix bars are manually path of movement of I brought into engagement with the slots in o the composer oneat a time, andto -accom-' plish this most conveniently a number of these pins are held between the thumb and first finger of the right hand while the composer is brought down across the bars by 5 means'of the milled head 18 upon the gear I shaft 15, which is grasped by .the fingers of the left hand and slowly rotated as each pin the proper is inserted 'by the right hand in slot of the composer frame. To make this ooperation' clear it will be observed that oneach bar is placed the entire al habet and such punctuation. marks and ot er characters as may at any time be required to'form a printed line. It is necessary in order to form 5 the line of characters over the slot of the castine box that the required matrices on the-ad-j I jacent bars should be brought in succession over the casting slot 6 which lies under the Iopening S between the central teeth of the o compo'serso that when the bars are laced'in e upper position the word or characters on t edges of the bars in the central slot between the-two central teeth can be clearly read, as

' shown in Fig. 14, where the hrase The Com- .mis'sio'ner of Patents has een com osed of the bars, and allis ready to castthe sliig from the matrices on their under surfaces.

.In order to bring each bar into position so that the pin thereonwill' engage one of-tlie -the front of the bed plate ispus'hed inward slots of the composer frameand the required character will be.

with a character on its uppersurtace where it equally distant one from another.

under the central tooth above the meld slot, each toothisprovid'ed' I provided with the character required. Thus if the letter A is tobe cast, the, pin on one of the bars is placed in the slot to the tooth A, when it will be found that the matrix A on the lower side of the bar is directly under the central opening'in the composer. This necessarily must be so sincethe right of there are the same number of characters on the teeth that thereare on the bars and they are placed in exactly 'the same ordgr and the central teeth ofthe composer 12 is blank "or without a character for the reason that the central slot being over the mold slot, it would not be possible to place a pin of a matrix bar therein'wh'en forming a Word for the reason that all the bars are blank underneath the pin. When all the bars are in place that are re uired to form a line, the compo ris.

pusherentirely across the o i b means ofth'e racks and pinionsdescribed, and

the points of the teeth of the composer frame 12 areinserted in guide slots 20 in the wall of i the opposite side of the opening, which serve to keep the teeth rigid and make the slime- -ment secure so that there will be no variation in the positions of the letters or characters" but they assume their proper position in the arise to keep the pins 8 in the slots between the teeth, the .p oints are slightly barbed or pro,-

line of type. .To serve as a temporary assist- Y jected into the slot on either side at 22', these projections serving as slight detents to holdthe pins from slipping out but-presenting no obstruction to slipping easily in. Guide lugs 23 upon the frame of the cornposer move in slots '24 in the lower plate of the main frame and keep the composer in perfect a'l inement H the casting box and slug.

with the slot of See FigsA, 6, and 7.

' In order to justify the series of 'trix bars'and to tighten them closely tegetlner so as to leave no spaces forliqui'd metal'to pass through between them,when they are in position over the mold slot, they are wedged together securely before the cast is taken. The matrix bars are all duplicates and are finely lie tapered at each end at 2'8. Aportiom of the bars are employed to form the line of type and a portion of the bars are brought together, end to and, between the words and pointed ends are wedged together to the lineandtoforrr-i the blank spaces. These bars have blank'surfaces beneath their pointed ends and beneath the central pins so'tha t these blank surfaces can be used as justifying spaces or for filling the whole or any portion of a blank space.

T A sliding detnt consisting of a 27 in and acts as agage to fix the'Wi-dth of the-ooh umnasseen in Figsii, 4;, 5, 8, and 14 and the inc is 'justified by means of the wedgingends justifying space either greater or less than the width of a single bar according to the length of the lap or engagement. The detent is providedwith the spring 29 which forces a keeper 30 into a notch 31 in the bed plate when the detent is adjusted to fix the width of'the column.

In order that it may not be necessary to I remove superfluous matrices from the trough.

when a line is formed, they are perforated at each end at 32 so that the detent bar 27 may pass through them asshown in Fig. 5 and a strong spring 33 between the line ofmatrices and side wall of the opening, keeps them closely together. This spring is shown of bow shape,but the shape is not important to the invention. This spring also serves to keep the bars in close contact during the operation of forming the line so that they will more readily keep theirplaces untillocked together by the detent and justified.

The manner in which a line of-matrices forming words is set up and justified to permit of casting a slug or line of type therefrom may be described as follows: The composer is first thrown to the back of the opening 2 by means of the milled head pinions and racks,

thus disclosing-the matrix bars, the pins of which 'may'now be thrown back to one or both ends of-this opening, the end walls of which will serve as stops to prevent their further movement and which serve to assemble them so that the pins can be readily grasped by the hand, or the pins may be assembled in a central line, between the central teeth of the composer before it is thrown back. The first word is then formed one letter at a time, by placing the pin of each matrix bar in turn in the slot of the composer adjacent to the tooth having the desired character or letter, thus bringing the desired character or letter over the casting slot. One word being formed two or more bars are separated by throwing in opposite directions until their wedging points slightly overlap and they meet to form a space and to justify the lme. The composer is brought forward from time to time to inclose the pins of the matrices, as they are placed to form words.

, between the rear wall and the detent.

The next words and spaces are formed in a similar manner until only a slight space is leftbetween the last bar and the detent which is to be filled by justifying the line, and the detent being adjusted to regulate the exact width, of the column, the line is finally justified by forcing the bars which form the spaces together until there is no opening left justified line is seen in Fig. 5. The remaining bars are kept in place by running the detent bar through the openings therein, and

'to) of each matrix the spring 33 serves to keep them together. To obtain further pressure upon the bars, if required, a forwardly turned lug 30 on the rear bottom edge of the composer is made to engage the inner bar and by means of a sharp turn on the milled head of the operating shaft at the moment of casting an additional ressure insures tightness of the joints.

urther instrumentality to bring the bars and composer into true and closer alinement with the casting slot during the act of casting is seen in the transverse grooves 34 upon the bar into which slight ri ges 35 upon the central teeth of the composer enter as seen in Fig. 15, and rooves 36 upon the lower edges of these bars into which enter ridges 37 upon the upper edges of the casting or mold slot. In order that the ridges upon the teeth of the composer may not interfere with the freedom of movement of the bars when used for justifying the upper edges of the points of these bars are cut away at 38. And the lining of the mold slot is vertically movable so that the ridges u op the edges of the slot can be lowered so that the bars can slide readily in the bottom of the trough before the casting is made. The ridges on the composer teeth do not inter-- fere when manipulating the matrix bars'to bring the proper characters in line since the teeth are not moved over them until they are placed.

Two forms of matrix bars are shown, one being perfectly straight with parallel sides and tapered ends, the other tapered toward each end from with tapered ends. Upon the tapered matrices the letters and characters are arranged with the wider letters in the central portion and the narrower letters toward the narrow extremities. Assoon as the casting has been made from the -matrices, the detent is withdrawn and the wedged bars released, the composer is then quickly drawn back by a rollin movement of the left hand upon the milled head of the gear shaft, and the matrix bars are quickly placed at either side of the opening by a sweep of the hand. It is not important toward what end of the opening the bars are placed before assembling them to form a line. In Fig. 4 the pins are shown in the central position, but an operator having good use of both hands could separate them, one half of the pins resting against one end of the opening, and the other half against the other end of the opening. The bars which are used as spaces must be first moved to opposite ends of the opening and when wedged together their pins would be approximately in line at a slight distance from the' the center and also provided which the (etent bar [these machines, devices greatly mu'ltiplied .openings in the bars coincide. The same result however could be .obtained if these bars were all moved to one side of the opening.

The advantages of this device over-the com licated automatic devices heretofore emp oyed for this purpose are obvious. In

in number and complexity are required to manipulate the large number'of separate mat- 'trices, tograsp and'hold. them'- singly and collectively, conduct them singly to the mold box and re-distribute them to their original positions'with such care and precision that they will not be confused or pied i i-the operation, and veryclosely and accurately fitting mechanism, liable to get out of adjustment, is indispensable to accomplish these results. Furthermore, expert mechanics must be constantly in attendance to keep the mechanism in working order. In devices of that kind the operator necessarily loses.

control of so many individual pieces and cannot be held responsible .if anything goes wrong.' In this device however all thematrices are formed in each bar, and cannot be misplaced or lost and no mechanism 3 is required'to control their movements, hence nothing approachable to. the proverbial l K 7 7 printers pie, canresult from their use, s nce they are all fixed in place and cannot be displaced 'out of their fixed order- No distributmg mechanism is required since they are returned to place bya sweep of the hand, or they need not be returned to theend of-the opening at all but -merely gathered together at the center. This simple method of composing leaves the bars Where they need no redistribution but may be. quickly placed back in line; It will also be seen that no adis at the other end. In this mventlon however,

ditional spacers are required, because each bar is capable of performing that function if its position requires such use. I

Heretofore matrix bars have been only pointed at one endand have been held moreor-less securely for longitudinal movement the duplicate doublyftapered extremities of each bar permit it to enter the series of bars,

from either side of-th'e casting or mold slot,

and when the bars are centrally collected together over the slot for the purpose of casting a slug, they can be dispersed in either direction, which ever happens to be the most convenient, without preventing their reassem bling .in whatever order desired. That is they have the function of interlocking from either end and adaptability for wedging together however placed, hence perfect reversie Patent, is: p
